The embodiment of the invention provides a voice interaction method, device and an intelligent terminal. The method comprises the following steps: detecting noise information of a current interactionenvironment when receiving a voice interaction instruction, wherein the noise information comprises noise volume and noise frequency; determining main frequency used for synthesizing response voice corresponding to the voice interaction instruction according to the noise frequency; synthesizing response voice according to the main frequency; determining volume at which the response voice is playedaccording to the noise volume, the noise frequency and the main frequency of the response voice; playing the response voice at the determined volume. Through the above technical scheme, the main frequency of the response voice and the playing volume can be dynamically adjusted according to noise information on the current interaction environment such that a user can acquire better voice interaction experience under any interaction environment.
